"idInjection": false doesn't work

[apijay]

I am trying set idInjection to false, so that I can set some other field as ID. Below is my
user-votes.json
{ "name": "user-votes-redis", "base": "PersistedModel", "idInjection": false, "options": { "validateUpsert": true }, "properties": { "user-name": { "type": "string", "id": true, "required": true }, "poll-id": { "type": [ "number" ] } }, "validations": [], "relations": {}, "acls": [], "methods": {} }
I get below error when i try to do following operations.

GET: /user-votes

POST:(works)

Seems to be working but can't find the index on redis.
